The ingredient narratives reshaping clean beauty.
Glycerin
aka glycerine · vegetable glycerin · glycerol
The most-used humectant in cosmetics globally — and arguably the most under-appreciated. Plant-derived (most modern cosmetic glycerin comes from soy, palm-free coconut, or rapeseed) and biocompatible at virtually any concentration. The 2025 'glycerin maxxing' trend (TikTok-fueled but formulation-real) sees brands increasing glycerin to 5–10%+ in barrier-led serums.
- draws water from the dermis and the air to the stratum corneum
- reinforces NMF and barrier hydration
- well-tolerated across all skin types and ages
- hydrating serums
- moisturizers
- cleansers
- anti-acne formulas
Effective at 2–10%; above 10% can feel sticky unless balanced with lighter humectants and silicone alternatives. Pairs with HA, PGA, sodium PCA, urea, and ceramides — the canonical NMF-mimicking stack.
In very low humidity, very high glycerin concentrations can theoretically pull water from the skin instead of into it — usually overstated, but layer over damp skin in dry climates.
Quietly trusted — too universal to controversially position. Look for 'palm-free' or vegetable-derived sourcing for clean credentials.
